Star Maker is a science fiction novel by Olaf Stapledon, published in 1937. The book tackles philosophical themes such as the essence of life, of birth, decay and death, and the relationship between creation and creator.

A pervading theme is that of progressive unity within and between different civilizations. Some of the elements and themes briefly discussed prefigure later fiction concerning genetic engineering and alien life forms. Arthur C. Clarke considered Star Maker to be one of the finest works of science fiction ever written.

A single human narrator from England is transported out of his body via unexplained means. He realizes he is able to explore space and other planets.

After exploring a civilization on another planet in our galaxy at a level of development similar to our own that existed millions of years ago thousands of light years from Earth (the “Other Earth”) in some detail, his mind merges with that of one of its inhabitants, and as they travel together, they are joined by still more minds or group-minds.
